In a crowd that included Chloë Sevigny, Maria Bello, Famke Janssen, Heather Graham and Josh Lucas, former heavyweight champion Mike Tyson (wearing a blue fur jacket, natch) stuck out like a sore thumb at the Artist’s Ball at New York’s Guggenheim Museum. He was apparently meeting Carmen Electra, who was late filming an episode of “Hope & Faith.” Perhaps to ease his discomfort, Tyson made a point of wishing holiday tidings to a line of guests at the bar. “God bless,” the pugilist told each and every one of them.

Equally ill at ease (or at least feigning such) were Adam Goldberg and Christina Ricci, who’ve just recently moved to Chelsea. What were they doing at the party, someone asked them.

“Exactly,” Ricci said, dripping with irony.

“We heard they were opening an envelope here, so we decided to come,” Goldberg countered.

In truth, the evening, sponsored by Dior, was hardly an envelope-opening affair. In fact, it was one of the best parties of the year. That’s partly due to it being the last major social event on the calendar for 2004, but also to Dior’s attention to scenic detail such as glitter on the dance floor, spotlights illuminating the ceiling of the museum and even chocolates in the restrooms. Contributing to the electricity was DJ Jeremy Healy, whose tunes were a mixture of the intellectual and the mainstream. (A fashion designer made out, in full view, with an unidentified gentleman to the sounds of Gwen Stefani’s “What You Waiting For?” “I haven’t seen something like that since high school,” hissed one guest.)

Delphine Arnault flew in just for the ball along with Dior chief operating officer Claus Dietrich Lahrs and his wife, Iris.

Also in the crowd were Gretchen Mol, Sean Lennon, Vanessa Carlton and Stephan Jenkins, Michael Stipe (who tends to wear Hedi Slimane onstage because it works “whether you’re in the front row or the back”) and Karen Elson. Tinsley Mortimer and Alek Wek wore matching fuchsia fox-fur stoles while the accessory of the evening was a pair of bracelets sported by Caroline Berthet and Tory Burch, who compared their wares.

“They’re Wonder Woman cuffs,” Berthet said. “I’m going to be a celebrity and not give them back.”

With no superhero bangles to defend herself, Alex Kramer was simply miffed upon seeing Janssen’s outfit. “We’re wearing the same dress,” she groused of their satin gowns. (Expect to find out who wore it better in next week’s Us Weekly. Our vote: Kramer.)

At least one person was excited to meet the “Nip/Tuck” and “X-Men” star — guest of honor Matthew Ritchie, who frequents the same Starbucks as the leggy actress. The artist joked that being chosen must have been “a weird clerical error.”

For her part, a chipper Graham said she’s transitioning into a new phase of her career as a producer. “I want to tell girly stories because I’m a girl and I like stories about girls,” she said. The benefits to producing your own film? “You can cast yourself,” she pronounced. “I got sick of trying to get people to cast me.”

As for her appearance at the Guggenheim, “I just thought a party in a museum sounded fun,” she explained. “And getting to wear a Dior dress makes it all the more funner.”

“I am of tradition, but that doesn’t mean I have an old outlook on life,” Hubert de Givenchy told WWD in an interview in 1978. The legendary designer, who died last week at the age of 91, achieved wide success soon after launching his own couture boutique in the early ’50s, but he refused to pine for that time. For the first time since its original publication, read our interview with Givenchy on his awe for Audrey Hepburn and looking forward. Link in bio. #wwdarchives #fbf (📷: Pierre Schermann)

About last night: @alexachung and @supergausa toasted the launch of their capsule collection. “It’s the shape that I love, so rather than amend the last and make the sole crazy or do anything wild, we just did really subtle additions that I think make it look really luxe-y,” said Chung. #wwdfashion (📷: Marc Patrick)
